1947 Julien MM5

Maurice A. Julien was a very well qualified engineer, known particularly for his work on the development studies of the Citroën Traction Avant, which made its debut in 1934. He retired to Toulouse at the beginning of the war, but during the Occupation, materials, especially gasoline, were very severely restricted, and Julien designed and built pedal cars as did Georges Mochet with his Velocars. In comparison, however, Julien’s Neocar was stylish and sleek, with its long hood, sweeping fender lines, and double kidney grille. It was mechanically more sophisticated than the average pedal car, as the front wheels were driven by cardan shafts, it employed a limited slip differential, and it used a derailleur, which permitted one or two people to pedal at different rates. Due consideration was given to the control of vibration. The last months of the Occupation saw second generation motorized versions in circulation. Finally, in 1944, the engineer had ready a much more sophisticated car, a coupe, which was close to the one that would debut at the 1946 Salon.

The two Julien cars that appeared at the Paris Salon of 1946 were set apart from the many other small vehicles on offer by the name of their distinguished creator. The Type VUP, which was recognizable by its open rear wheels and full-width axle, was powered by a flat-twin motor. The similar MM5 had narrow, enclosed rear wheels and was powered by a single-cylinder motor. Both cars were fitted with sliding windows. The VUP would not see production. The following year was taken up with dealings with government bureaucracy to receive permission to develop the MM5 as a production car. Detail improvements were attended to, resulting in better ventilation and braking and a slightly enlarged motor—a result of vigorous road testing.

The car that made its appearance at the Paris Salon of 1947 was a beautifully proportioned cabriolet with sensuous curved body lines and attractively rounded fenders, which flowed together at the front, underneath an exquisitely-shaped pointed hood. One could immediately see the heritage of the Traction Avant in the strong central-welded bulkhead structure-cum-windshield frame curving up from the sills. The front hood was hinged from this structure below the windshield, and the entire rear engine cover hinged upwards from behind the seat, allowing unhindered access to the motor and drivetrain. The sliding windows had now been replaced by windows hinged at the door-top to fold down into the interior of the car and into the doors themselves.

Julien reorganized his company as la Société des Automobiles M.A. Julien, now based in Paris, had re-entered the microcar market with a more modern design. The Julien MM7 shown at the 1949 Paris Show appeared to be a copy of Rovin’s D3. There were the same pontoon-shaped, interchangeable front and rear fenders. It differed from the Rovin in the semicircular side windows, like those of the Champion 400 Coupe, and in the headlamps built into the front fenders, which the D4 would get in 1954. Despite this revamping, nothing much would come of Julien’s brave final attempt.
